Fybogel FibreChews Citrus

What Is Fybogel FibreChews Constipation Relief?

Struggling with constipation is more common than most people realise. In fact, it affects around one in seven adults in the UK at any given time. Fybogel FibreChews constipation relief offers a genuinely different approach — instead of dissolving a sachet in water, you simply chew a citrus-flavoured tablet and wash it down with a glass of water. That convenience alone makes it a popular choice for people who find traditional fibre drinks unpleasant or impractical. You can browse our full range of constipation treatments if you'd like to compare your options before deciding.

Each chew contains ispaghula husk, a natural plant-derived fibre that has been used in the UK for decades to support regular bowel habits. The citrus flavour makes it noticeably more palatable than many other fibre supplements, and the chewable format means there's no mixing, no measuring, and no waiting for a powder to dissolve.

How Does Fybogel FibreChews Work to Relieve Constipation?

Ispaghula husk is a bulk-forming laxative. Unlike stimulant laxatives, it doesn't force the bowel to contract — it works with your body's natural processes instead. Here's what happens after you take a chew:

• The ispaghula husk absorbs water as it passes through your digestive tract.
• This increases the bulk and softness of your stool.
• A larger, softer stool is easier to pass and triggers the natural urge to go.
• Regular use helps establish a more consistent bowel routine over time.

Because it works mechanically rather than chemically, it's considered one of the gentler options available without a prescription. That said, drinking enough fluid is absolutely essential — without adequate water intake, ispaghula husk can actually worsen constipation or, in rare cases, cause a blockage.

Who Should Use Fybogel FibreChews?

Fybogel FibreChews are suitable for a wide range of people dealing with constipation, including those who simply don't get enough fibre through their diet. They're also commonly used to manage symptoms associated with conditions like irritable bowel syndrome (IBS), haemorrhoids, and diverticular disease, where maintaining soft, regular stools is important. If you're also dealing with piles, our haemorrhoids and piles collection has additional products that may help alongside a fibre supplement.

This product is generally suitable for:

• Adults and children aged 12 years and over
• People who prefer a chewable format over sachets or liquids
• Those managing constipation related to a low-fibre diet
• Individuals with IBS where constipation is the predominant symptom

Is Fybogel FibreChews Suitable for Long-Term Use?

Fybogel FibreChews constipation relief can be used regularly as part of a long-term bowel management plan, particularly for people with chronic constipation or conditions like IBS. However, if your symptoms persist beyond a few weeks without improvement, it's worth speaking to your GP to rule out any underlying cause. Persistent constipation can occasionally signal something that needs further investigation.

Store the chews below 25°C in a dry place, away from direct sunlight and out of reach of children. Check the expiry date on the packaging before use. If you're also managing digestive discomfort alongside constipation, our IBS and cramps collection may offer complementary support.

This product is a medicine. Speak to your doctor or pharmacist before using if you have an underlying medical condition or are taking other medicines.

What Is Fybogel FibreChews Citrus and What Is It Used For?

Fybogel FibreChews Citrus is an over-the-counter medicine containing ispaghula husk, a natural dietary fibre derived from the husks of Plantago ovata seeds. It is used to treat constipation and to help maintain regular bowel movements. It may also be recommended as part of the management of conditions where soft, regular stools are beneficial — including irritable bowel syndrome, haemorrhoids, and diverticular disease. The NHS describes bulk-forming laxatives like ispaghula husk as usually the first type of laxative recommended for constipation.

What Do You Need to Know Before Using Fybogel FibreChews Citrus?

Do not use Fybogel FibreChews Citrus if any of the following apply to you:

• You have difficulty swallowing or a known narrowing of the oesophagus or gut
• You have a sudden change in bowel habit lasting more than two weeks that has not been assessed by a doctor
• You have a bowel obstruction or faecal impaction
• You are under 12 years of age
• You are allergic to ispaghula husk or any other ingredient in the product
• You have phenylketonuria (check the full ingredients list for phenylalanine content)

Speak to your pharmacist or GP before using this product if you have diabetes, as ispaghula husk may affect blood glucose levels. Also seek advice if you are taking any other medicines, as fibre supplements can affect how quickly other drugs are absorbed.

Known interactions to be aware of:

• Ispaghula husk may reduce the absorption of some medicines, including lithium, digoxin, and certain antidiabetic drugs — separate doses by at least 30–60 minutes
• May affect the absorption of fat-soluble vitamins if taken in very large amounts over a long period

How Should You Use Fybogel FibreChews Citrus?

Always use this product exactly as described on the packaging or as directed by your pharmacist. The most important thing to remember is to drink plenty of fluid — at least one full glass of water (150–200 ml) immediately after chewing each tablet. Without adequate fluid, the product cannot work properly.

1. Take one Fybogel FibreChew from the pack.
2. Chew the tablet thoroughly in your mouth — do not swallow it whole.
3. Immediately drink a full glass of water or another cold drink (at least 150 ml).
4. Repeat up to twice daily as needed, ideally after meals.
5. Continue to drink plenty of fluids throughout the day.

What Are the Possible Side Effects of Fybogel FibreChews Citrus?

Like all medicines, Fybogel FibreChews Citrus can cause side effects, although not everyone experiences them. Most side effects are mild and tend to improve after the first few days of use as your body adjusts to the increased fibre intake.

Common side effects:

• Bloating and a feeling of fullness
• Flatulence (wind)
• Abdominal discomfort or cramping, particularly in the first few days

Less common side effects:

• Allergic reactions — including skin rash, itching, or in rare cases, difficulty breathing (seek immediate medical attention if this occurs)
• Oesophageal or intestinal obstruction if taken without sufficient fluid
• Worsening of constipation if fluid intake is inadequate

If you experience any severe or unexpected symptoms, stop using the product and contact your GP or pharmacist. You can also report side effects directly to the MHRA via the Yellow Card scheme. If you're managing related digestive discomfort, our indigestion collection may offer additional support.

How Should You Store Fybogel FibreChews Citrus?

• Store below 25°C in a dry place
• Keep away from direct sunlight and moisture
• Keep out of the sight and reach of children
• Do not use after the expiry date printed on the packaging
• Do not dispose of medicines via wastewater or household waste — return unused medicines to your pharmacy

For further guidance on managing bowel health, the NHS provides detailed advice on constipation, including lifestyle changes that can support the effect of bulk-forming laxatives. Increasing dietary fibre, staying well hydrated, and taking regular exercise all contribute to better bowel regularity alongside treatment.
